JSON_DECODE()

Synopsis

Returns the string value of a JSON object key from a string containing a JSON array.

Description

The JSON_DECODE function retrieves the value of the given variable name and parses it as JSON, returning the value at a specified key. If the key cannot be found, an empty string is returned.

Syntax

JSON_DECODE(varname,item[,separator[,options]])
Arguments

  • varname - The name of the variable containing the JSON string to parse.

  • item - The name of the key whose value to return.
    Multiple keys can be listed separated by a hierarchy delimeter, which will recursively index into a nested JSON string to retrieve a specific subkey's value.

  • separator - A single character that delimits a key hierarchy for nested indexing. Default is a period (.)
    This value should not appear in the key or hierarchy of keys itself, except to delimit the hierarchy of keys.

  • options

    • c - For keys that reference a JSON array, return the number of items in the array.
      This option has no effect on any other type of value.
